Few would question the positive impact technology has had on education. E-mail, the Internet, and software programs have sped up the pace of work, connected students to experts worldwide, and brought libraries right to the doorstep. A 1999 survey showed that more than 25 million children ages 2 to 17 are online, a number that has tripled since 1997. Of those, more than 70 percent of teens use the Web regularly. But with the surge of information comes a greater burden on teens to manage time. Unlike their parents, who typically had to take more initiative to create interruptions from homework, many teens are finding technology floods them with ways to lose concentration.
